I am having very slow performance running Blender
Make sure you have your video drivers up to date since Blender's UI is run entirely through OpenGL. Just search for your graphics card (GPU) online. If you do not know what model of GPU you have, then try going to the GPU brand's website usually you can find which brand of GPU you have somewhere on your computer's case or the box it came in. The brand will usually have an easy way to find out what GPU you have and provide you with updates.
